Is disoduim phosphate covalent or ionic?
Disodium phosphate is an ionic compound, not a covalent one. It consists of positively charged sodium ions and negatively charged phosphate ions, which are held together by electrostatic attractions.
Is Monopotassium Phosphate ionic or molecular?
tricalcium phosphate is an ionic compound do to the fact that it is the bonding of a metal and a nonmetal. it is usually only a molecular compound if it is a bond between two nonmetals such as oxygen and hydrogen.
How are the layers of the earth held together?
The layers of the Earth are held together by gravity and the intense pressure from the weight of the overlying layers. This pressure causes the layers to be compacted and stick together, forming a solid structure.
Why is ammonia a gas and sugar a solid at room temperature?
Ammonia is a gas at room temperature because its molecules are non-polar, allowing them to escape as a gas easily. Sugar is a solid at room temperature because its molecules are held together by relatively strong intermolecular forces, such as hydrogen bonding, keeping them in a solid state.
What can be separated into its elements fairly easily?
Compounds that are held together by weak intermolecular forces, such as salt or sugar, can be separated into their elements fairly easily through processes like dissolution and evaporation. Additionally, mixtures of elements can be separated through physical methods such as filtration or distillation.
What connects the backbone of the DNA molecule together?
The DNA backbone is made of phosphate group and deoxyribose, and they are held together by covalent bonding.
How are the backbones of DNA held together?
The backbones of DNA are held together by covalent bonds, specifically phosphodiester bonds. These bonds form between the phosphate group of one nucleotide and the sugar group of another nucleotide, creating a strong polymer structure that makes up the backbone of the DNA molecule.
What is sugar moiety?
Depending on the molecule, the "sugar" may change, but a moiety is like a subdivision of a functional group. In DNA we have nitrogenous base held by a sugar phosphate backbone. "Sugar moiety" refers to the deoxyribose sugar that is part of the DNA backbone.
What are the two sides of the DNA and the helix held by?
The two sides of DNA are the sugar-phosphate backbone, which provides the structural support for the molecule. The helix is held together by hydrogen bonds between the nitrogenous bases on each side of the DNA molecule.
What the structure of DNA?
DNA has both primary and secondary structures, on a primary level it is made up of three main molecules a sugar and phosphate group backbone and attached to this backbone on of the four nitrogen bases. On a secondary level the sugar phosphate and necleotides run anti parallel to another strand of DNA and form a helical structure by wrapping around itself and is held together by hydrogen bonds.
The structure of a DNA molecule resembles the shape of a twisted ladder. In this model which part of the ladder is made of sugars and phosphates?
Each strand is made up of a chain of nucleotides.The two strands are held together by hydrogen bonds between adenine and thymine and between guanine and cytosine. The hydrogen bonds of DNA are analogous to the rungs of a twisted ladder. The sugar-phosphate backbones of the double helix are analogous to the sides of a twisted ladder.
What type of chemical bond holds together the backbone of a strand of DNA?
Covalent bonds between a sugar molecule (deoxyribose) and a phosphate group make up the backbone of DNA. These are very strong covalent bonds and are broken only with great expenditure of energy--x-rays, for example.
How are nucleic acids held together?
Nucleic acids are held together by phosphodiester bonds between the sugar and phosphate groups of adjacent nucleotides in the backbone of the molecule. Additionally, hydrogen bonds between nitrogenous bases in complementary strands help stabilize the double-stranded structure of DNA or RNA.
What chemicals connect to what in a dna strand?
The backbone of the DNA molecule is composed of alternating deoxyribose sugars and phosphate groups. The nitrogen bases are bonded to the sugar molecules. The two strands of DNA are held together by hydrogen bonds between the nitrogen bases of both strands.
What structures hold the chromosomes together?
A chromosome is made up of different parts: nucleotides (base pairs), sugar and phosphate (a full chromosome contains other stuff too but that is for a more complex explanation). The nucleotides are what codes for proteins, so that is the useful or 'coding' information. The sugar and phosphate form a sugar-phosphate backbone, holding all of the nucleotides together. (type base pairs into Google image to find a picture of this). A Chromosome is a long strand of these nucleotides which are held together with the sugar-phosphate backbone. IF UR TALKING ABOUT MEIOSIS then they are held together by spindle fibers.
What is the most basic DNA structure?
The most basic DNA structure is a double helix composed of two complementary strands of nucleotides held together by hydrogen bonds. Each strand consists of a sugar-phosphate backbone with nitrogenous bases (adenine, thymine, cytosine, and guanine) attached to the sugars.
What type of bond keep DNA together?
The backbone of DNA is held together by covalent bonds. DNA is made up of nucleotides, a sugar (2-deoxyribose) attached to a base and a phosphate group. The backbone consists of alternating phosphate and sugar residues joined together by phosphodiester bonds. Hydrogen bonds are involved in stabilising the helix along with what are called base stacking where the aromatic rings in the bases align to minimise the "free energy" these are essentially short range intermolecular forces and are not usually considered to be "bonds".
